Outstanding Picture
I Love White Water Kayaking—August 28, 2025
Wow, it's huge (77" model)! I upgraded from an old 50" plasma TV, it's light enough that the original mount was able to hold it. Impressive picture quality and very bright; I actually turn the brightness down to 50% in a semi dark room. The sound is good. Installation on a ceiling hanging mount was a little challenging because it's so wide you can't reach the screws from either side if it is close to the wall, so I had to reach from below. It has no bezel on top so it looks and feels fragile, but following the instructions to not hold it by the top, we had no issues. I disabled TruMotion because I can't stand the "soap opera effect". I didn't bother to connect it to the internet because I use external video sources. This was a refurbished unit, but I couldn't see any indication of it ever being opened. The shipping was a little weird, I received an envelope with instructions to call to arrange a freight delivery date, but it all went fine. I'm happy with my purchase. Read more

Great picture. Took me a while to find the aspect ratio control so I could watch "Casablanca" in the original 4:3. No RCA plugs for audio out, lucky my receiver accepts optical input. Read more

Jp—April 19, 2025
Though there was some confusion on the arrival date and then the actual arrival of the tv… it was thought to be lost in shipping but was not… I am totally pleased with this tv and the remote is a lot better and more convenient than the Samsung tv and remote I had previously. The color is great and the sound is exceptional!! Read more
